Cal Auto Diagnose & Repair in San Lorenzo

He’s our go to mechanic now. Honest and does a good job with all repairs. Thank you Don!

Don(owner) is an amazing mechanic and does excellent work! Honest and no fluff. Very nice guy too!

Don is the man! Oil change and air filter change for a good price and did it the same day when a bunch of other shops told me to come in the next morning

I have been coming to this shop for the longest and I can say that they go beyond the work that is needed !! They are friendly and so very helpful !! I really appreciate them

I have been using Cal Auto for over 10 years. Henry is honest, personable and he leads with integrity. He has folks who come from SF to have their cars worked on because they trust him. I always recommend him.

Guy came out diagnosed my cat in 1 minute for free and sent me on my way. Best service I ever had at a mechanic. Thanks asian dude Haha.

If you are looking for a super clean waxed floor, free coffee kind of shop keep looking...but if you are like me- have an older car and like honest work at a great price - go talk to Henry at this place. He has been doing business in San Lorenzo/San Leandro for a long time and is really fair with the cost of work. They have looked at my car for free when i have been worried about a sound or a possible issue. They have even done small fixes for free. Since my car is old -whenever i go on a long road trip i have them check my car out to make sure it can make it. Any work i needed done has been great ❤ so far so good with this place!

I just purchased a car recently that had extensive engine repair done at this place (their name is on the receipts) and the workmanship was beyond unacceptable! I am a mechanic with over 35 years experience and after only spending a couple of hours on it, so far I have found the following issues: Oil level was over full. 4 bolts that hold the headlights and the grill in (which have to be removed to do the repairs they did) were only finger tight (they forgot to tighten them). Oil filter was way over tightened. Leaking oil like crazy because they did not torque the bolts on the timing cover to their specifications and they failed to replace a $3.00 O-Ring on the cam actuator. I’m afraid I’m going to have to re-do all of the work they did, just so I know it was done right. Also, take note - this place has no reviews anywhere (accept for this one), so buyer beware.
